UC Berkeley, partnering with Nokia and Navteq, have been working on a project to use GPS data from cell phones to create a traffic monitoring network that will allow users to get real-time traffic conditions, as well as relay their own information to the network. Dubbed the Mobile Millennium Project, a public beta will be launching on Monday in the San Francisco Bay area and, if you live in the area, you can participate by signing up at the project’s website. If not, they’ll be streaming live video of the launch starting at 8:30am PST on Monday, so you won’t missing a single exciting minute!
